The emirate of Sharjah borders with Dubai to the south, Ajman and Umm Al Quwain to the north and Ras Al Khaimah to the east. It is the only emirate that overlooks the coastline on the Persian Gulf to the west and the Gulf of Oman (Indian Ocean) to the East, with the eastern Sharjah coastal towns of Kalba and Khor Fakkan.

The city is a center for culture and industry, and alone contributes 7.4% of the GDP of the United Arab Emirates. The city covers an approximate area of 235 km2 and has a population of over 800,000 (2008). The sale or consumption of alcoholic beverages is prohibited in the emirate of Sharjah without possession of an alcohol license and alcohol is not served in Sharjah hotels, restaurants or other outlets due to the Muslim majority in the area. This has helped Sharjah increase the number of Islamic tourists who visit the country. Sharjah has been officially named as a WHO healthy city. The 2016 edition of QS Best Student Cities ranked Sharjah as the 68th best city in the world to be a university student. Sharjah is regarded as the cultural capital of the UAE and was the Islamic culture capital in 2014. Sharjah was named World Book Capital for 2019 by UNESCO.
